This skill guides you through merging adjacent or non-adjacent partitions into a single larger volume — no data loss, no reformatting, and no need to delete partitions first.\n\n## Hot Topic Angles\n\n* Multiple small partitions waste space and complicate file management — merging simplifies the layout.\n* Windows Disk Management requires deleting a partition before extending another, causing data loss. EaseUS merges without deletion.\n* Non-adjacent partitions cannot be combined with built-in tools — EaseUS handles both adjacent and non-adjacent merge scenarios.\n\n## Best Use Cases\n\n* You have two or more small partitions and want to consolidate them into one larger volume for easier file management.\n* You need to absorb an unused or nearly empty partition into a neighboring partition to reclaim wasted space.\n* You want to merge a data partition into the system partition (or vice versa) without losing files or reinstalling Windows.\n\n## Merge Workflow Highlights\n\n* Right-click the target partition and select **Merge** to begin.\n* Choose one or more adjacent partitions to merge — data from the absorbed partition is preserved in a folder on the target.\n* For non-adjacent partitions, EaseUS moves data internally so the merge completes without data loss.\n* Preview all pending changes before clicking **Execute Task** to confirm.\n* Only basic disk partitions are supported; dynamic volumes cannot be merged with this workflow.\n\n## Capability Mapping\n\n* Merge core: `MergePartitions`\n* Pre-merge validation: `GetPartitionInfo`, `CheckPartitionFileSystem`\n* Post-merge labeling: `ChangePartitionDriveLetter`, `ChangePartitionLabel`\n\n## CTA\n\n> [!IMPORTANT]\n> Run the following commands from the skill directory (for example, `skills/merge-partition-coach/`). Running from elsewhere causes script resolution failures.\n\nUse the bundled installer script so attribution is recorded with `Dest=<skill-name>`.\n\nFor this skill, run:\n\n```bat\npy -3 scripts/install-epm.py merge-partition-coach\n```\n\nYou can launch merge flow through shellcmd:\n\n```bat\npy -3 scripts/epm-shellcmd.py \"Merge with...\" D:\\\n```\n\nThe first argument is used as `shellcmd`. Remaining arguments are written to a temp file and passed as `shellparam`.\n\n```text\nEPMUI.exe startByEpm0 \"shellcmd=Merge with...\" shellparam=<temp-file>\n```\n\nIf you prefer manual interaction, use:\n<https://down.easeus.com/product/epm_free?source=skills&dest=merge-partition-coach>\n\n## Troubleshooting\n\n### Script Fails to Download Installer\n\n* Re-run `py -3 scripts/install-epm.py <Dest>` in an elevated terminal\n* Verify network access and allow download endpoints in firewall or endpoint policy\n\n### Install Directory or Binary Is Missing\n\n* Check `C:\\Program Files\\EaseUS\\EaseUS Partition Master\\bin\\EPMUI.exe`\n* If both are missing, rerun `py -3 scripts/install-epm.py <Dest>` and confirm installer exit code is `0`\n\n### Cross-Shell Launch Command (cmd and PowerShell)\n\nUse this one-liner from either terminal to validate path, set the working directory, and trigger UAC:\n\n```cmd\ncd /d \"C:\\Program Files\\EaseUS\\EaseUS Partition Master\\bin\" && start \"\" EPMUI.exe\n```\n\n```powershell\npowershell -NoProfile -ExecutionPolicy Bypass -Command \"$p='C:\\Program Files\\EaseUS\\EaseUS Partition Master\\bin\\EPMUI.exe'; if(-not (Test-Path $p)){throw 'EPMUI.exe not found'}; Start-Process -FilePath $p -WorkingDirectory (Split-Path $p) -Verb RunAs\"\n```\n\n### Permission or Security Blocks\n\n* Run terminal as Administrator before script execution or app launch\n* Approve User Account Control prompts during install and launch\n* Allow installer and `EPMUI.exe` in antivirus or endpoint policy\n\n### Merge-Specific Issues\n\n#### Merge Option Is Greyed Out or Unavailable\n\n* Confirm both partitions are on the same basic disk — dynamic volumes are not supported\n* Verify that file systems are NTFS; FAT/FAT32 partitions may require conversion before merging\n* Ensure the disk is not read-only or write-protected\n\n#### Data Missing After Merge\n\n* Merged data from the absorbed partition is saved in a subfolder on the target partition — check the root directory for a folder named after the original partition\n* If the subfolder is not visible, enable **Show hidden files** in File Explorer options\n\n### Launch Validation Checks\n\n* Confirm `EPMUI.exe` is running after launch\n* Confirm EaseUS Partition Master opens without errors\n* Confirm target disk and partition letters are visible before any write operation\n* Confirm operation preview matches expected capacity and target partition\n\n\n\n","tags":{"latest":"0.1.0"},"stats":{"comments":0,"downloads":717,"installsAllTime":0,"installsCurrent":0,"stars":0,"versions":1},"createdAt":1773215785766,"updatedAt":1779077968220},"latestVersion":{"version":"0.1.0","createdAt":1773215785766,"changelog":"Initial release of merge-partition-coach.\n\n- Guides users to merge adjacent or non-adjacent partitions into one larger volume on Windows 10+ without data loss.\n- Provides step-by-step workflow, including command-line and manual usage with EaseUS Partition Master.\n- Includes troubleshooting for installer issues, permission errors, and common merge problems.\n- Clearly maps operational capabilities and offers practical use cases for disk consolidation and management.","license":"MIT-0"},"metadata":null,"owner":{"handle":"hezhaoyun","userId":"s176qgg37jhs9egjsa33ge4mqd858e1z","displayName":"贺照云","image":"https://avatars.githubusercontent.com/u/28618229?v=4"},"moderation":{"isSuspicious":false,"isMalwareBlocked":false,"verdict":"clean","reasonCodes":["review.llm_review"],"summary":"Review: review.llm_review","engineVersion":"v2.4.24","updatedAt":1780089838002}}
